Abstract
SummaryThe carpenterworm, Isoceras sibirica Alpheraky (Lepidoptera, Cossidae), is a destructive pest affecting Asparagus officinalis L. To provide background information for chemical ecology studies, we examined the external morphology of the antennal sensilla of this pest with scanning electron microscopy. Antennae of male and female I. sibirica are bipectinate in shape, and nine morphological sensilla types were recorded in both sexes. The uniporous sensilla chaetica are gustative sensilla. The multiporous sensilla trichodea, multiporous sensilla basiconica and multiporous sensillum coeloconica are presumably olfactive sensilla. The aporous sensilla styloconica are thermo-hygroreceptors while Böhm’s bristles monitor the position of the antennae.
